UNITED STATES PATENT OFFICE- EDWARD A. PEASLEY, OF PANCOA STBURG, OHIO.

Ll FTING-JACK.

SPECIFICATION forming part of Letters Patent No. 322,315, dated July 14,1885.

f Application filed November 28, 1884. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD A. PEASLEY, of Pancoastburg, in the county ofFayette and State of Ohio, have invented certain new and usefulImprovements in Lifting-Jacks; and I do hereby declare the followingtobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in lifting-jacks; and it consistsin the combination of the standard having ratchet-teeth with a slottedtoothed hanger which is rigidly secured at its upper end to the upperslide, a second slide which is connected to the hanger through its slotby a suitable bolt, and the operating-lever provided with teeth upon itsinner end, so as to engage with the teeth of the hanger, and suitablepawls which are connectcd to the slide and which engage with theratchets on the standard, as will be more fully described hereinafter.

The object of my invention is to provide a lifting-jack which is adaptedfor many different uses, both in raising and lifting, and in which theslides are alternately moved by the same lever.

Figures 1 and 2 are side elevations of a lifting-jack embodying myinvention,taken from opposite sides. Fig. 3 is a plan view of the same.

A represents the standard, which is provided with a suitable base, B,and which has a series of ratchets, 0, formed in one of its edges.Passed down through the top of this standard are two slides, the upperone, D, of which is provided withthe pawl E, and to which the slottedtoothed hanger F is rigidly secured. This hanger projects downward anysuitable distance,and has the slot I through it made of a lengthcorresponding to the distance the lower slide, J, is to be moved by theoperating-lever L. The lower slide, J, is loosely connected to thehanger by means of the bolt N, which passes loosely through the slot.The operating-lever is pivoted upon the lower slide, and is providedwith teeth, so as to engage with the teeth of the hanger. The

lower slide is also provided with a pawl, P, for the purpose ofsupporting the slide in'any position that may be desired.

. When the two slides are at their lowest positions upon the standardand the lever is opouter end raised upward. The pawl of the upper slidethen catches in one of the ratchetteeth 0, for the purpose of preventingthe upper slide from descending, while the lower slide is moved upwardin a similar manner upon the standard. When the downward stroke ofthelever ceases, the pawl of the lower slide catches in one of theteeth, so as to hold the slide in position, and then as the outer end ofthe lever is forced downward the upper slide is again forced upward. Thetwo slides are operated alternately simply by operating the lever like apump-handle.

By connecting a jack to one of the slides devices of any kind can beraised upward from the ground, and where a pin is passed through a holein the top of the standard, so as to act as a stop for ablock or othersimilar device, the jack can be used as a press or as a monkey-wrench.

Having thus described my invention, I claim- 1. In a lifting-jack, thecombination of the standard provided with ratchetteeth with two slides,each one of which is provided with a pawl, the slotted toothed hanger,and the operating-lever provided with teeth, substantially as shown.

2. The combination of the standard, the upper slide provided with apawl, the slotted toothed hanger which is secured rigidly thereon, thelower slide, which is connected to the hanger by means of abolt, andwhich is provided with a pawl, with the toothed operati ng-lever whichis pivoted upon the lower slide, substantially as set forth.

In testimony whereof I affix m y signature in presence of two witnesses.

EDWARD A. PEASLEY.
